We’ve had the King for a number of years and have been very happy with it. So when the time came to replace it, the King 40 was the obvious choice. Tail end of last season, the thermostat lost its tension and stove got really hot. I watched the video on here how to restore tension, and it felt much better. However, it has never worked as well as the old stove or how it was before it lost tension. It seems very very sensitive when I adjust it, and I never know if it is going to take off and be too hot or not (even when it is set to the normal middle setting). If it seems like it is getting too hot and I adjust it slightly down, all of sudden, it is down under the active zone again. Something is definitely up, but I don’t know what and how to fix it. Any help appreciated.
